I disagree, I think the visuals, Gantt charts, are precisely the kind of "PM speak" that can be understood. Sure it won't solve anything as long as C-suite and investors do innovation signaling but that itself can only last so long.

I think the point is that clarity has been published many times.

Humanity knows how to solve starvation. Clear routes were laid out long ago. The work is in adoption.

The alternative viewpoint is that if there weren’t people who continue to try to advocate for a better world, the world we’d live in would be even worse.
